Maintaining continuous access to web content

ABSTRACT

An approach for providing a framework to maintain continuous access to web content bookmarked in a browser, the framework comprising web content storage, change detection and change notification. Embodiments of the present invention create and store a snapshot of bookmarked web content with a version number in a repository and the snapshot is replaced by a new snapshot whenever bookmarked web content is updated, while access to previously versioned snapshots is maintained. Change detection comprises automatically subscribing to content update notification services provided by a web content provider and receiving updates, comparing the content of a most recent snapshot with the web content available from the content provider and detecting a change to the bookmarked URL. Keywords from a snapshot can be used to relocate web content at a new URL and a web browser user is notified whenever a change to bookmarked web content is detected.

BACKGROUND OF THE INVENTION

The present invention relates generally to the field of bookmarked webcontent, and more particularly to maintaining continuous access tobookmarked web content.

The bookmarking of web content is a useful feature employed by mostinternet web browsers enabling a user to quickly navigate to the webcontent as needed, saving the user time because they do not have toperform a new search or manually enter a web address every time theyneed to access the web site they have in mind. Bookmarked content canalso be stored in cache memory so that it is more quickly accessed interms of computer processing time. However, web content, such as a webpage, can be modified by a web content provider, moved to a differentUniform Resource Locator (URL) or a different web server, or removed.Accordingly, web browser based applications, known as “plugins,” can beemployed to allow a web browser user to maintain continuous access tobookmarked web content in the event normal access has been disrupted.

DETAILED DESCRIPTION

Embodiments of the present invention recognize the need for anintegrated solution to maintain continuous access to bookmarked webcontent that requires minimal user intervention. Web content isbookmarked because the information it provides is valuable and useful toa web user, yet there are a number of circumstances where continuousaccess to this information can be interrupted. These circumstances caninclude when a web content provider or author decides to update thecontent of a bookmarked web page, when a bookmarked web page isrelocated to a different URL, when the web content is removed by thecontent provider or when the provider is experiencing an outage on theirhost server. These and other similar types of circumstances can cause aweb user to temporarily or permanently lose access to content andinformation they need and can, in some cases, cause disruptions in workproductivity and efficacy. It is with this in mind that embodiments ofthe present invention propose a solution designed to automaticallyhandle these interruptions to normal, continuous access to bookmarkedweb content with little user intervention. Further, embodiments alsoprovide the feature of being able to save, on local or remote storage,snapshots of multiple versions of web content that has been editednumerous times, which can be highly desirable to web users who need toreference past versions of web content.

The present invention will now be described in detail with reference tothe figures. FIG. 1A is a functional block diagram illustrating adistributed data processing environment 100 in accordance with anembodiment of the present invention. Distributed data processingenvironment 100 comprises computing device 102, web server 110 andremote storage 120, interconnected over network 108.

Computing device 102 can be a laptop computer, tablet computer, netbookcomputer, personal computer (PC), a desktop computer, a personal digitalassistant (PDA), a smart phone, or any programmable electronic devicecapable of communicating with web server 110 and remote storage 120 vianetwork 108. Computing device 102 has web browser 104 installed whichcomprises web content manager plugin 106, a framework designed to help auser maintain continuous access to bookmarked web content. Computingdevice 102 can include internal and external hardware components, asdepicted and described in further detail with respect to FIG. 5.

Web server 110 can be any type of computer having the necessary hardwareand software to support a web site and comprises content provider 112.Content provider 112 creates, manages and updates web content, such as,but not limited to, web sites and/or web pages (and associated contentsuch as, but not limited to, text, images, audio files, video files,etc. . . . ), to be accessed on the internet via web browser 104. Remotestorage 120 can be one or more computer servers, such as, but notlimited to, a Cloud service, which store files and data externally tocomputing device 102.

Network 110 can be, for example, a local area network (LAN), a wide areanetwork (WAN) such as the Internet, or a combination of the two, and caninclude wired, wireless, or fiber optic connections. In general, network110 can be any combination of connections and protocols that willsupport communications between computing device 102, web server 110 andremote storage 120.

FIG. 1B is a block diagram of web content manager plugin 106 comprisingcontent update notification subsystem 114, content storing subsystem 116and content reacquiring subsystem 118. Content update notificationsubsystem 114 can detect if content provider 112 supports or offers aweb content update notification service and send any informationrequired such as, but not limited to, an internet protocol (IP) address,to subscribe to that service. In the event a notification of updated webcontent is received from content provider 112, content updatenotification subsystem 114 can alert the browser user by various means(e.g., a pop-up notification window, a “push notification” on a mobilecomputing platform, an alert icon placed next to the bookmark in thebrowser, etc. . . . ). It should be understood that this process ofalerting the browser user can be referred to as “change notification”and can occur whenever a change to bookmarked web content is detected byweb content manager plugin 106.

Content storing subsystem 116 can create and store one or more snapshotsof web content, such as, but not limited to, at least a portion of thecontent of a web page, in a repository on local (i.e., on computingdevice 102) and/or remote storage when the web content is bookmarked bya user or when previously saved bookmarks are detected by web contentmanager plugin 106. New snapshots can be created and saved manually, ona predetermined schedule (either default or user configured) or whendetected changes have been made to the web content by content provider112 and the new snapshots will be given a number indicating a versionfor the repository. It should also be noted that the capability ofembodiments to detect changes to bookmarked web content in any mannerdiscussed herein can be referred to as a “change detection” feature ofthe framework.

According to one embodiment of the present invention, a snapshot of webcontent available from content provider 112 can be stored on local orremote cache memory for rapid access to content that is available evenif web server 110 is experiencing an outage. When the web content isupdated, the snapshot in cache memory can be replaced by a new snapshotof the web content and the snapshot being replaced can be saved to amore permanent form of storage (i.e., persistent storage, which will bediscussed in FIG. 5) to be referenced as needed by the user. Multiplesnapshots of web content with version numbers can be saved for referencein the repository as the web content changes over time. It is to befurthermore understood that the repository comprises any storage media(i.e., local and/or remote) used to store the one or more snapshots ofweb content for a bookmark.

Content reacquiring subsystem 118 provides the capability to maintaincontinuous access to web content in the event of disruptions to normalaccess, such as, but not limited to, broken web links (when a URL nolonger points to a valid web address) or URL redirects (when a uservisiting a first URL is forwarded to a second URL). Broken links and URLredirects can be detected either when a user selects a bookmark orduring a predetermined scheduled scan of bookmarked content. If a URLredirect is encountered when a bookmark is accessed, content reacquiringsubsystem 118 can update the URL for the bookmark to the redirected URL.According to embodiments, if no URL redirect is encountered but thebookmarked web content has a broken URL, content reacquiring subsystem118 can extract portions of, or keywords from, a most recently storedsnapshot of the web content and use it to perform a web search via apublic search engine (e.g., Google, Yahoo, Bing, etc. . . . ) to eitherrelocate the web content at a new URL or provide consolidated searchresults to the user that recommend one or more URLs reflecting similarcontent.

Turning to FIG. 2, a flowchart 200 is provided depicting initialoperational steps of web content manager plugin 106 when a web page isbookmarked, in accordance with an embodiment of the present invention. Aweb browser user creates a new bookmark for a web page, at block 202,and content update notification subsystem 114 determines, at decisionblock 204, if the content provider 112 supports web content updatenotification. This can be accomplished, for example, by a scan of themetadata contained in an HTTP response header field to determine ifcontent provider's 112 host server (i.e., web server 110) supportsupdate notification functionality (i.e., an update service) and whatinformation needs to be provided to subscribe for update notifications.If the content provider 112 does not provide update notification, webcontent manager plugin 106 moves to decision block 302 as will bediscussed subsequently. If the content provider does support updatenotification, any information required to subscribe to the updateservice is sent, at block 206, to content provider 112. In the eventthat content provider 112 publishes an update of the bookmarked webcontent and the update service is subscribed to, web content managerplugin 106 will update, at block 208, the bookmark appropriately (suchas updating the metadata for the bookmark) and provide a notificationand/or indicator to the user to alert them of an update. A notificationand/or indicator can include, for example, a pop-up window indicatingthat web content has been updated by content provider 112, an alert iconon the updated web content in the list of bookmarks and/or a pushnotification for a mobile computing platform. Once a bookmark has beenupdated in this manner and the user has been notified, embodimentsproceed to decision block 302, dealing with storing a version ofbookmarked web content.

Moving to FIG. 3, a flowchart 300 illustrates operational stepsassociated with content storing subsystem 116, according to anembodiment of the present invention. If a user decides to manually storea snapshot of bookmarked web content or if content storing subsystem 116is preconfigured to automatically store web content, at decision block302, content storing subsystem 116 determines, at decision block 304, ifthe web content is available at the original bookmarked URL. If the webcontent is not available at the original URL, embodiments move todecision block 402, as will be described subsequently. If the bookmarkedweb content is available at the original URL, content storing subsystem116 determines, at decision block 306, if the web content has changedsince the last time a snapshot of the web content was stored in local orremote memory (i.e., the most recently stored snapshot). This can bedone by comparing the content (e.g., text, images, embedded files, etc.. . . ) of the most recently stored snapshot with the web contentavailable from content provider 112 and determining, according to apredetermined and optionally configured user threshold, if the webcontent has changed enough from the most recently stored snapshot for anew snapshot to be stored in the repository. For example, if thecomparison of content shows that the web content has changed by apredetermined threshold of 25% or more compared with the content of thestored snapshot in cache memory, then a new snapshot of the web contentwill replace the snapshot in cache memory, which will be stored inpersistent storage.

In another manner of determining, at decision block 306, if the webcontent has changed from a most recently stored snapshot, the metadataof the most recently stored snapshot of web content can be compared withthe metadata of the web content available from content provider 112 toscan for any changes to a date or time stamp, for example. If it isdetermined that the bookmarked web content has changed in any mannerpreviously discussed, at decision block 306, content storing subsystem116 will determine the storage type in which to store a new snapshot ofthe web content, at block 308. It should be understood that the term“cache update policy” can be used for this process of replacing the mostrecently stored snapshot by detecting that a change has occurred to theweb content in any manner discussed herein.

The storage type can be a preconfigured choice set by a user of eitherlocal or remote storage. Remote storage can be the default option forweb users on a mobile computing platform. Remote storage has theadvantage of allowing multiple authorized users across a network toaccess the most recent and previously stored snapshots of stored webcontent from a plurality of computing devices. Some examples of remotestorage and network protocols that can be accessed by multipleauthorized users can include, but are not limited to, a cloud service,file transfer protocol (FTP) and Web-based Distributed Authoring andVersioning (WebDAV).

Once the choice of storage has been selected, a snapshot of thebookmarked web content is stored, at block 310, and web content managerplugin 106, at block 312, can wait a predetermined time interval beforeprompting the user to store the web content or automatically storing theweb content (starting at decision block 302) according to a userconfigured or default predetermined schedule. If bookmarked web contenthas not changed according to the predetermined threshold, at decisionblock 306, content storing subsystem 116 will wait the predeterminedtime interval before attempting to store the latest version ofbookmarked web content. If the web content is no longer available at theoriginally bookmarked URL, web content manager plugin 106 proceeds todecision block 402.

It is to be understood that if, at decision block 302, a user wishes tostore a snapshot of web content and none already exist in the repository(i.e., a user is storing the first snapshot for a bookmark), embodimentswill proceed to decision block 304 to ensure that the web content isstill available at the same URL, skip decision block 306 (since nosnapshot exists with which to compare to the web content) and proceed toblock 308 to determine the storage type.

FIG. 4 depicts a flowchart 400 showing the operational steps of contentreacquiring subsystem 118. If, at decision block 402, a redirect to anew URL is provided when a bookmark is accessed, content reacquiringsubsystem 118 will automatically update the URL of the bookmark toreflect the change and content update notification subsystem 114 willcheck, at decision block 204, to determine if content provider 112provides an update notification service if, for example, contentprovider 112 has moved to another web server 110. If an accessedbookmark no longer leads to a valid URL and no URL redirect is provided(i.e., a loss of reference to content), content reacquiring subsystem118 will extract keywords or portions of text from the most recentlystored snapshot and use them in a web search engine, at block 406, tolocate the web content at a new URL. Content reacquiring subsystem 118can determine, at decision block 408, if the web content has beenlocated at a new URL if the content of a particular web search resulteither exactly or very nearly (e.g., within approximately 95%similarity) matches the keywords or portions of text from the storedsnapshot used in the web search. If the web content is not located, atdecision block 408, consolidated search results can be presented to theuser, at block 412, to recommend similar content (e.g., other web pagesproviding similar content) and the user prompted as to whether or notthey want the bookmark removed, at decision block 414, which can alsodelete any stored snapshots of the web content on local or remotestorage, depending on where the versions of the web content are stored.If, at decision block 408, the web content is located at a new URL,content reacquiring subsystem 118 will update the URL and metadata ofthe bookmark accordingly, at block 410, and determine, at decision block204, if content provider 112 supports update notifications. Thisprocess, wherein content reacquiring subsystem 118 handles a situationwhere a bookmark is accessed but the URL no longer points to a valid webaddress and no URL redirect is provided, can be herein referred to as“broken link handling.”

It should be noted that at any point in time, though not explicitlyshown in the figures, if a bookmark is accessed and a URL redirect isencountered, the URL for the bookmark will be automatically updated byembodiments of the present invention to reflect the change. It is alsoto be understood that web content manager plugin 106 provides a userinterface (UI) which allows the web user to configure the settings forany of the processes discussed herein such as, but not limited to,storage of web content snapshots, broken link handling, the cache updatepolicy and update notifications.
